Foredom Diamond Polishing Disc 6'' Dia. 80grit .5'' Ah

Description:

Diamond Polishing Disc 6'' dia. 80Grit .5'' AH is a versatile medium-coarse dental disc used for shaping and contouring restorations with greater smoothness than traditional coarse abrasives. Its 80-grit diamond surface offers a valuable transition between aggressive material removal and preliminary smoothing, making it essential for dental lab workflows involving ceramics, zirconia, alloys, and acrylic components. With a 6-inch diameter, the disc provides broad working coverage, allowing technicians to polish large surfaces or multiple units efficiently. Its size also supports stable rotational balance, reducing vibrations and enhancing precision during shaping. The .5-inch arbor hole ensures compatibility with standard lab polishing motors, providing a secure and dependable fit. This disc is typically used after rough grinding with 40- or 60-grit discs. It helps refine contours, smooth sharp edges, and establish more defined anatomy before moving to intermediate finishing. Its diamond bonding delivers consistent abrasion, minimizing heat and reducing the risk of micro-fractures in sensitive materials like ceramic or zirconia. Technicians rely on this disc for adjusting crown morphology, refining denture borders, smoothing implant prosthetic frameworks, and contouring composite or acrylic surfaces. The controlled cutting action makes it easier to achieve proportional shaping without unintentionally removing excessive material. This ensures that restorations maintain their strength and function before final finishing stages. Overall, the 80-grit 6-inch diamond polishing disc is a valuable tool for dental laboratories, providing reliable shaping performance and smooth surface refinement crucial to fabricating high-quality dental prosthetics.
